after logging out of the application. The vulnerable parameter is
p_home_url. When a value is passed to this parameter, it becomes
persistent in nature and remains active until the session is expired.
The vulnerable Link:

An attacker can construct a URL in this way and forces user to redirect to
the malicious link after logging out of the application.This type of
vulnerability can be exploited by malicious attackers to launch phishing
attacks etc
